You are designing a ski jump ramp for the next winter olympics. youneed to calculate the vertical height^ h from the starting gate to the bottom of the ramp. theskiers push off hard with their ski poles at the start, just abovethe starting gate, so they typically have a speed of 2.0^m/s as they reach the gate. for safety, the skiersshould have a speed of no more than 30.0^m/s when they reach the bottom of the ramp. youdetermine that for a 86.0^ kg skier with good form, friction and air resistance will dototal work of magnitude 4000^ j on him during his run down the slope. what is themaximum height ^h for which the maximum safe speed will not be exceeded?
